FARM-GATE.

Specification of Letters Patent No. 23,339, dated March 29, 1859.

To oZZ whom it may concern:

Be it known that I, GEO. IV. BAKER, of Neponset, in the county of Bureauand State of Illinois, have invented a new and useful Improvement inFarm-Gates; and I do hereby declare that the following is a full, clear,and exact description of the saine, refer-ence being had to the annexeddrawing, forming -part of this specification, in the several figures ofwhich similar characters of reference denote the same part.

Figure l is a top view of the gate and mechanism operating the same.Fig. 2 is a front elevation of gate and section on a1 0c.

This is a farm gate designed to be opened and closed by the passingof awheel of the vehicle over levers on each side of the gate, thecombination of devices by which the operation is effected, constitutinglny invenlEOII.

In the drawing B B are the sections of the gate provided with rollers rfor traversing a rail track a.

At the outer extremities of the sections are bars Z) b between which arethe bent extremities of rods o c, attached to slotted levers Z Z underthe surface of the road. These levers are connected with the rods f f,by pins in their extremities entering the slots. These are supported inbearings c e so as to reciprocate therein and by their movement actsupon levers Z and through rods c c on the sections of gate. The rods ff' have jaws z' z' provided with rollers embraced in the curved slotsfm, m of a slide -piece D suspended under the roadway by the bearings inwhich the rods at its extremities rest.

To the ends of rods a are attached chains p p, leading to the lowerextremities of the weighted levers C, the upper arms of which are abovethe road, and in a vertical position owing to the weight W at the lowerend.

The wheel of the vehicle coming in contact with the lever C depressesit, and by reason of connections before stated draws the slide piecehalf its length. The rollers in the jaws of rods f, following slots fm,mI the two sections of the gate separate and the vehicle passes through.The wheel is then made to act upon the lever C on the opposite side,moving t-he slide D into the position from which it started and closingthe gate.

I claim- The slide D and levers C C in combination with the rods f flevers Z Z rods c c and bars Z), arranged for joint operation inconnection with the gate sections substan tially as set forth.

In testimony whereof I have hereunto signed my name before twosubscribing witnesses.
